Hmph. I would have preferred to see we stayed away from 'restore'
(and used 'checkout' instead, if you must use a Porcelain command),
so that the "fix" can go to maintenance tracks, if distro packagers
choose to backport it.
Isn't the machinery for "git status" (in wt-status.c) mature enough
to allow us to learn what got changed all in-core, without spawning
an external process these days, though?
